New Delhi: Delhi's climate begins to get polluted every year in November. This includes stubble burning in the fields of Haryana and Punjab among other reasons. In this order, NASA shared a photo on his Twitter handle. In which the reason behind the smoke that Delhi is wrapped in thick layers these days is given. Pawan Gupta, a scientist at the Research Association (USRA) at the Marshall Space Flight Centre in NASA, responded to the increase in fire activities and said that about 22 million people were affected by the stubble burning incident in the field in 1 day. A picture taken from a satellite in NASA clearly shows how the smoke from Punjab and Haryana is increasing towards Delhi. Photos of November 11 show the national capital Delhi and the surrounding area wrapped in a thick layer of smoke. In addition, the photos have red dots which are seen displaying large-scale fires in some areas of Punjab, Haryana and Pakistan. Though the contribution of stubble in fog and smoke in Delhi NCR this year is said to be low, NASA has said that Punjab and Haryana have been burnt the highest number of stubble since 2017. The record for stubble burning was maintained in 2016. A total of 8,4884 cases have been registered since then. Scientist Pawan Gupta has said that 7,2373 cases of stubble burning were reported in Punjab throughout the season in 2020, while 7,4015 cases have been reported till November 16 in 2021. This has been followed by Punjab's highest stubble burning in 2021 since 2017. The case of stubble burning was recorded every year from 2017 to 2019. Smoke from crop fires in northern India blanketed Delhi and contributed to soaring levels of air pollution. https://t.co/Pe30imj6xV pic.twitter.com/RyNEmVcbXx NASA Earth (@NASAEarth) November 18, 2021 We decided to roll back agricultural laws: PM Modi Breathing in Delhi-NCR becoming even more severe!
